Landlord charging tenant extra rent for parking on common property

Hi everyone, I am not sure if this has been asked and answered in previous forum topics.

I bought a flat in July, there is a driveway on the property at the side of the building, but no car spaces, there is always a car parked in the driveway belonging to a tenant in the downstairs flat. The car doesn’t block anything as the driveway doesn’t go anywhere.

On Sunday night I noticed the car wasn’t there so I parked in the driveway and went into my flat. About an hour later the tenant knocked on my door asking if I could move my car as he needed to park there. I apologised and said I thought it was common property. He said no that he paid extra rent to park in the driveway.

I didn’t think that sounded right, so I spoke to the strata manager yesterday who confirmed that the driveway is common property.

What can we do? I am wondering if we can force the landlord to pay all the extra rent they have received to the strata fund?

I feel badly for the tenant, but the landlord is in the wrong here.

Can anyone advise?

Thank you

Sassy
